APPARATUS FOR TREATING SILK IN HANKS.

Application filed March 28, 1908.

To all whom it may concern:

Be it known that I, FRITZ LINDENMEYER, a citizen of the Swiss Republic and resident of Basel, Switzerland, have invented new and useful Improvements in Apparatus for Treating Silk in Hanks with Soap-Lather and the Like, of which the following is a full, clear, and exact specification.

For the purpose of ungumming raw silk it has recentlybeen frequently treated with soap lather (the so-called lathering treatment.) For this treatment of the silk the need has been experienced for a practical and simple apparatus,which admits of the treatment of the silk in the form of hanks, and moreover admits of the putting in and taking out of the silk hanks, which in consequence of the tender nature of fibers require careful handling, into the receptacle for the treating or out of the same in the simplest, most convenient and least damaging way.

The object of the present invention comprises an improved apparatus for treating silk in hanks with soap lather and the like, in which the drawbacks hitherto experienced are remedied by the provision of a row of revoluble rollers placed one beside another in the receptacle and adapted to receive the silk hanks, the said rollers beingfreely supported at one end in an open bearing and at the other end being so connected to a support by means of a hinge and a terminal plvot coupled to a driving wheel, that they can be raised or turned upward upon their hinge connection for the purpose of the easier inser tion of the silk hanks 1n the rece tacle or for the urpose of the easy remova thereof out of t e receptacle without disengaging the driving mechanism of the rollers. By means of this device not only is the putting of the silk hanks into the receptacle and their removal from it rendered more easy, but also the handling of the separate rollers themselves made easier for the workmen than if these were supported at both ends in open bearings.

The accom anying drawing illustrates a constructiona form of the invention, which is adapted for the treatment of silk hanks with soap lather and subsequently for washing the same.

Figure 1 is a partial longitudinal section through the apparatus perpendicular to the silk hanks rollers. The apparatus is also pro- Specification of Letters Patent.

vided with a spraying tube device serving for the washing of the silk hanks. Fig. 2 is a transverse section through the ap )aratus. Fig. 3 shows the bearings of the sill: hanks rollers. Fig. 4 serves to illustrate the construction of one of these rollers. Figs. 5 and 6 are partial sections transversely through the r0 Fig. 6 also shows a modification of the spraying tube device for washing the silk hanks.

In these drawings, a indicates a receptacle adapted for the treatment of the silk hanks, preferably of galvanized sheet iron, in which the soap liquid intended for the formation of the soap lather is put and which contains in its lower part one or more steam coil tubes Z) devised for the heating thereof, preferably of galvanized gas pipes or of copper pipes. In the upper part of the receptacle a the rollers c destined for the reception of the silk hanks are arranged parallel to one another. These rollers consist each of a circular set of longitudinal rods (1 referably of galvanized iron, which are held at the requisite distances apart in slots of the disks 0. At one end the rollers are each provided with a terminal pivotflocated in an open bearing 9 (Fig. 3), and each roller is supported at its other end by means of a hinge h and an end pivot i proceeding from a part thereof on supporting bars 70 which in the interior of the receptacle extend along a side wall thereof, in such a manner as to be capable of being raised or turned upward upon the hinge 7b. This raising of the rollers c has to be done when the'silk hanks are to be suspended into the receptacle a or are to be removed therefrom, and are to be placed for this purpose upon the rollers c or to be removed from them.

The end ivots i of the rollers c are shaped quadrangu ar (Fig. 3, see also Fig. 6) and are inserted in a corres ending opening of a sleeve j, which is revo uble in the supporting bars 7c, and possesses between these a worm wheel m, which engages with a worm n. On the turning of the worm wheels or the rollers c are consequently revolved on their own axes, which brings about a continuous turning of the silk hanks in the bath of lather. The rollers 0 can be lifted up, without thereby causing their connection with the driving wheels m to cease. Moreover they can in case of need be very conveniently entirely removed from the receptacle a because after ers taken at various points thereof;

simply lifting up the rollers their end pivots i can be withdrawn from the sleeves 'All the worms n are placed upon a common shaft 0, which can be revolved by means of a crank handle p (or by means of an automatic driving device of any kind) As already mentioned, the apparatus illus trated is also devised for the purpose of being utilized after treatment of the silk hanks with soap lather, for the purpose of washing the same. There is therefore provided at the upper edge of the receptacle a a sprayin tube device, which comprises a principa l tube q and a number of spraying tubes 1* branching off from the former at right angles, and placed parallel and vertically over the rollers 0 (Figs. 15) whereby the washing liquid is directed downward in vertical sprays upon the silk hanks already treated with soap lather. This is the preferred arrangement of the spraying tubes. In the modification shown in Fig. 6, the spraying tubes r are changed in their position relative to the rollers c and are so formed that they can discharge the washing fluid upon the hanks of each two rollers. The principal tube 9 of the s raying device is in both cases revoluble a out its own longitudinal axis, so that the sprayin tubes 0 and r can be turned upward when the rollers c are to be raised. At one end the principal tube g is releasably attached by means of a bayonet joint or the like with a supply tube (not represented in the drawing.

In the lower part of the receptacle a there are arranged at the lower end of the space occupied during the operation by the silk hanks, certain revoluble paddles s, which are placed vertically during the treatment of the silk hanks with the soap lather in order not to hinder the formation and rise of the latter, but when the silk hanks thus treated are to be washed, then the paddles s are turned into the position indicated by dotted lines in Fig. 2 in order that they may overlap one another at the edges and thus form a continuous intermediate bottom, upon which the washing fluid separated from the lathering fluid which is underneath it can be collected. The paddles or plates 8 are arranged side by side on different heights in the receptacle so that the intermediate bottom formed in the manner above described by them will have a certain inclination toward an outlet opening a usually closed by means of a sliding door If in the said receptacle (2, so that the washing liquid which trickles down upon the intermediate bottom can flow off through the opening a. The turning of all the plates 8 can be effected by means of gear wheels engaged with a common rack. The division above described is only necessary in the case when, as in this instance, the receptacle a is to be used for washing as well as lathering, without permitting the lathering liquid to flow ofi, an arrangement whichhas a certain advantage in that for a subsequent treatment with soap lather the filling again with the fluid is avoided. Moreover as the liquid remains in the lower part of the recep tacle it is only necessary after a washing to turn back the plates 8 into their upright position again, in order to allow of the unimpeded production and rise of the soap lather. When required by circumstances, however, the intermediate bottom might be dispensed with and before the washing operation the soap liquid might be drawn off temporarily into another receptacle provided for 1t, and be subsequently drawn back into the receptacle a for a repeated lathering process. Finally it may further be stated that the spraying tubes of the spraying device might have another position relatively to the rollers than that illustrated in the drawing although that represented in the Figs. 1 to 5 is the preferred one.

lVhat I claim is:

1. In an apparatus for treating silk in hanks with soap lather and the like, the combination with a receptacle of a row of revoluble rollers to receive the silk hanks, placed one beside another, freely supported at one end in an open bearing and connected at the other end to a support by means of a hinge and a terminal pivot coupled to a driving wheel, so that they can be raised or turned upward upon their hinge connection for the easier insertion of the silk hanks in the receptacle or for the purpose of the easy re moval thereof out of the receptacle without disengaging the driving motion of the rollers.

2. In an apparatus for treating silk in hanks with soap lather and the like, the combination with a receptacle of a row of revoluble rollers to receive the silk hanks, placed one beside another, each formed of a circular set of longitudinal bars, freely supported at one end in an open bearing and connected at the other end to a support by means of a hinge and a terminal pivot coupled to a driving wheel, so that they can be raised or turned upward upon their hinge connection for the easier insertion of the silk hanks in the receptacle or for the purpose of the easy removal thereof out of the receptacle without disengaging the driving motion of the rollers.

3. In an apparatus for treating silk in hanks with soap lather and the like, the combination with a receptacle of a row of revoluble rollers to receive the silk hanks, placed one beside another, freely supported at one end in an open bearing and connected at the other end to a su port by means of a hinge and a terminal pivot detachably coupled to a driving wheel, so that they can be raised or turned upward upon their hinge connection for the easier insertion of the silk hanks in the receptacle or for the purpose of the easy removal thereof out of the receptacle without disengaging the driving motion of the rollers.

4. In an apparatus for treating silk in hanks with soap lather and the like, the combination with a receptacle of a row of revoluble rollers to receive the silk hanks, placed one beside another, freely supported at one end in an open bearing and connected at the other end to a support by means of a hinge and a terminal ivot coupled to a driving Wheel, so that t ey can be raised or turned upward upon their hinge connection, spraying tubes being arranged above the said rollers to allow of the washing of the silk hanks treated with soap lather and the like and being branched off from a common supply tube rotatable upon its own longitudinal axis to permit the raising of the spraying tubes.

In witness whereof I have hereunto signed my name this 16th day of March 1908, in the presence of two subscribing witnesses.
